[G2 Q&A, Help & Troubleshooting] thefallen924:
quick update guys..after 3 days of flawless operation, i installed the google experience launcher. within 30 seconds, the issue arose. opened notepad and got the ekg lines. uninstalled, cleared cache and dalvik through cmw, and hasnt happened since. within the 3 days that it was running well, i tried everything i could to get it to exhibit the issue..from rapid swiping to writing paragraphs, to using the phone on the charger when it was warmer than usual. as soon as i installed that third party launcher it was pretty much automatic.
[G2 Q&A, Help & Troubleshooting] billykxda:
Yep - welcome to the club. There are some gremlins in that G2 code, for sure.

1. I suggest not going looking for the issue, or trying to trigger it, just enjoy your G2.

2. If/when the problem arises, turn your screen off/on. It'll reset and the behavior will be gone for a while - maybe quite a while.

3. If it really pisses you off, return/exchange your G2.

4. Go back to #1.
[G2 Q&A, Help & Troubleshooting] INCREMENTAL:
Hey guys so i got my G2 last night and loving it so far other then this stupid touch screen issue. I have a couple of questions and wanted some input on my case particular.

Reading through the posts mine is described the same as everyone elses but mine seems to happen often. For the first day with it its happened quite a few times and already pretty annoying.

If its a software issue then i dont see switching the phone out will do any good right? I dont see this problem going away for a whole day let alone 2 or 3. Turning off the screen does help sometimes but not always. It just seems mine is causing me more issues more often then most others.

I did put a screen protector on the first few hours ive had it. Could this be affecting the issue more?

Thanks for any input.
[G2 Q&A, Help & Troubleshooting] billykxda:
The frequency of this issue is not material. It can happen often on day 1, or not happen until month 2. No rhyme or reason regarding that.

Swapping the phone out for a new one is not a sure solution. Some don't report back with repeat problems after exhanging, plenty of owners report back saying that over time, it's just the same with the new device. I opted to replace mine. For me, the issue was apparent on Day 4 with the new device. To return or not to return is a personal choice. I've seen no highly repeatable evidence that getting a new G2 "fixes" the problem.

The highest frequency of occurance for me was when I didn't have a screen protector or case on my G2 - the first few days of ownership. Given that, I wouldn't be quick to draw the conclusion that protectors and cases prevent the issue. I'd say that they have absolutely nothing to do with it.

Give your G2 a few days. It may not reoccur for some time. You probably have 14 days to swap-out, right?

Check to make sure that you have near half of the total RAM available. There is some speculation that we may be running into a low-RAM condition that is causing this issue - but that's just a guess as of now. Having tons of processes running at once can't be good.

Hope this helps!
[G2 Q&A, Help & Troubleshooting] INCREMENTAL:
Thanks for the reply and all ur helpful knowledge on this thread. Ill give it a few days and see how it does. Just about 30mins ago it has already flipped out on me and it took 3 times shutting the screen off for it finally to work right. I checked the ram and have around 800mb free. Are you thinking maybe this is linked to the graphical ram?

Thanks again, Ill report back n a few days.
[G2 Q&A, Help & Troubleshooting] billykxda:
800mb free RAM is probably typical - so no issue there.

I have no idea of which type of memory might be involved.

Still in the learning phase with this issue.
[G2 Q&A, Help & Troubleshooting] INCREMENTAL:
Well that didnt take long, this is really annoying. Im finding more times then not when i turn the phone on its messed up. And turning the screen off literally does nothing most of the time. I really wanna like this phone but right now my 1yr old Note 2 works way better then this damn thing.
[G2 Q&A, Help & Troubleshooting] billykxda:
That sounds pretty severe.

Have you tried a Factory Reset?

That may be a good next step.

-bk
[G2 Q&A, Help & Troubleshooting] INCREMENTAL:
No i havent, was gonna give it some time but i have almost no choice, i literally turned the screen off 4 times before it worked right again. Ill factory reset it later tonight. If that doesnt work ill swap it out for another and hopefully get one that works better. U would think if its a software issue then every phone should act the same regardless and to me thats not seeming like the case.
[G2 Q&A, Help & Troubleshooting] billykxda:
The best thinking on this issue is that it probably is a software issue, but as with many software-related issues, there are environmental conditions that affect how the software operates, such as installed apps, running processes, settings and usage patterns.

Sorry to hear that you are in such a frustrating situation. I'd do the factory reset and if that doesn't quiet things down, exchange it.

We really have to get LG's attention regarding this issue. Please feel free to "vent" on the LG G2 Owners Community on Google+.
[G2 Q&A, Help & Troubleshooting] INCREMENTAL:
Thanks 4 the link. Ill check it out. Im swapping it out tonight, if i get another bad one then its gone for good. Love the phone but nearly half the time I turn it on the phone is useless.

I do also guess it might be the gram that causes this issue...!
[G2 Q&A, Help & Troubleshooting] cggorman:
I've had this problem since week one. It happens every couple days. Giving the screen a good cleaning fixes it EVERY time.

The early GNex handsets had bad volume controls that were fixed with a kernel update. I'm hoping LG will issue a screen fix with the next official update. If not, I'll continue to keep it clean.
[G2 Q&A, Help & Troubleshooting] billykxda:
Do you turn your screen off when you clean it?

If so, it may be the case that it's the screen being turned off that is the temporary fix - not the cleaning of the screen.

There are lots of reports from G2 users suggesting "fixes" for this issue that appear to be anecdotal, including:

- Cleaning the screen

- Installing or removing a case

- Installing or removing a screen protector

- Turning some settings on, some settings off

- Installing a new launcher

- Rooting and installing a new ROM

- Installing or uninstalling a new theme

- Installing or uninstalling a new keyboard

- Calibrating the motion sensor

- Running a specific utility app

- Doing a factory reset

- Replacing the device

All of these "solutions" have been suggested by G2 owners, but unfortunately, none of them have a high rate of repeatability. Did these "fixes" appear to work for the person that reported it? Absolutely! I don't doubt that. But, none of them work reliably for the majority of G2 owners that have noticed this defect.

One thing that seems to work, albeit temporarily, is simply turning the screen off/on. But even this sometimes only resolves the issue for a very brief time for some.

Via this thread we are hoping to hear from enough G2 owners to try to isolate the issue, possibly identify a fix, but certainly to get the attention of LG, who has the responsibility of addressing this defect.
[G2 Q&A, Help & Troubleshooting] billykxda:
It's a spooky bug - for sure.
[G2 Q&A, Help & Troubleshooting] billykxda:
I wanted to share that I logged a "Voice of the Customer" report at LG regarding this G2 issue that is being forwarded to LG Management and the Software Engineering team. They are promising to get back to me via phone or email. We'll see...

[G2 Q&A, Help & Troubleshooting] billykxda:
You may be on to the core issue here, but it's still too early to say for sure.

I have not had this issue reoccur for a while now. I do tend to chuck running apps at points during the day, hoping this has have an effect.
[G2 Q&A, Help & Troubleshooting] billykxda:
I've heard of this issue. Try starting a thread specifically on this topic - you might get some quick help.
[G2 Q&A, Help & Troubleshooting] sjs87:
I've been having touch screen issues since yesterday after having the G2 for about 2 months now. I posted in another thread but I just got some new info.

Mine is different from most I dont have the "ekg" lines at all. Mine are perfectly straight. What I have is a dead spot on the screen . I have a quickmemo screen shot below. This dead section is there through out the entire UI and all apps just like it is for the ekg lines that most people experience. Once this started though, it hasn't gone away through numerous reboots and a factory wipe/reset. Knock knock is also not functioning at all anymore.

Either way, I've chalked it up to hardware because I just now got a message when I turned the screen on telling me that the LCD is damaged. It wouldnt let me screen shot the image but I found it in another thread here which is also attatched below. I'm willing to bet that the ekg lines others experienced are also caused by hardware damage. I'm probably going to eventually order a new LCD and attempt to replace it and see if it resolves anything because I don't expect LG to do anything about it. They've never done anything in the past for their customers and i'm well pass the return period.

I told myself I would never get another LG because I've had a terrible track record with all their phones including a Nexus 4. But I wanted to give LG one last shot with this phone and honestly so far it's been my favorite device overall. But after this, I'm officially done with them.
[G2 Q&A, Help & Troubleshooting] billykxda:
Sorry to hear this. Honestly, if I had a touchscreen that was totally unresponsive to the point where knock on/off didn't work and entire portions of the screen didn't register touch, I'd be annoyed as well. Surprised to hear that your N4 was disappointing - I've heard nothing but good things about that phone.

Best of luck with your next device.
[G2 Q&A, Help & Troubleshooting] sjs87:
yea man, the N4 was just terrible for me honestly, A bunch of lag, terrible battery life, terrible data connection, etc. Other people I know personally have had nothing but good stuff to say though aside from the battery, Also had the old LG thrill which was a waste and a couple from the optimus line.

Now I did have one major drop (slid off of a cars trunk while in motion) but the phone was in a rugged 2 peice case so no visible physical damage was taken And it worked fine for a couple weeks after the incident. Again though, that doesn't explain the numerous cases of others that are having this issue that we know about. But even then, my S2 skyrocket that lasted me since release just recently malfuntioned because of water damage and I abused the crap out of that phone. And my old inspire HD that was dropped from a second floor with no case still functions 100% with a shattered screen.

The Z1 was my other choice but I decided against it soley because of the larger bezels. I think I'm gonna go for that next, but I'll see how long I can hold out just in case anything else releases any time soon. I'm spoiled with the SD800 chips now so my next device at least has to meet that requierment. lol
[G2 Q&A, Help & Troubleshooting] billykxda:
OP updated with findings from post #91.
[G2 Q&A, Help & Troubleshooting] gotwillk:
is this happening on all variants? i'm on the vzw version and it happens but not as bad as described in OP or post #91. the only thing that affects me is the typing. i use Swype and i noticed that after i've swiped my words for a long while, chances are the responsiveness and accuracy will start to deteriorate. i turn my screen off and on when it gets really bad because i can't stand it anymore.but thats really the extent of it for me. i get the weird webpage fast scroll thing too but that doesn't bother me as much as the typing.
[G2 Q&A, Help & Troubleshooting] billykxda:
Reports of this issue are across all variants. I have VZW as well. The OP is an aggregation of of symptoms - not my experience at any one time! And in post 91, I went looking to verify symptoms. So, once I noticed that the condition was there, I tried this and that just to confirm that they are all verified symptoms of this issue.

I guess we all have different thresholds for software defects. At first, I was quite put-off by these behaviors since my G2 was new, now I can work-around them a little better. Still, the G2 has this software defect that causes some a little grief, but causes others plenty of heartburn, resulting in repeated returns and customers turning to other devices.
[G2 Q&A, Help & Troubleshooting] lunargecko:
Many of my phones have spazzed out in the past, including the LG G2. For me it's very easy to accidentally touch the side of the screen with another finger due to the tiny bezels.

My Dad also got an LG G2 and accidentally broke the digitizer on the top side of the screen by accidentally knocking on one its corners, also getting the LCD damage system message. It seems to be very easy to damage, again due to the small bezel.
[G2 Q&A, Help & Troubleshooting] wesnile:
I had an issue where an entire "row" of the screen was untouchable. I could no press any buttons on that part of the screen. It included the Play Store's install button. This issued caused the knockon feature to not work as well. I also found that trying to draw a line caused a jagged change at the point of the untouchable row.

I ended up exchanging the phone and am hoping this won't continue to be an issue on the new phone.
[G2 Q&A, Help & Troubleshooting] billykxda:
Everything you state here are classic symptoms. Spending time in the browser is surfacing as a one pretty dependable trigger.

Do you recall where you went in your browser and can you go do it again in the same sequence - if possible? I only half-expect for it to be 100% repeatable in this manner, but it would be cool if you could make it spazz again.

I am planning to do the same the next time this issue arises on my G2.

Dropbox

Just installed dropbox.

I have 4.4kitkat.

then my phone went crazy. the touchscreen was spazzing everywhere.

even turning off/on the screen couldn't fix it.

right after uninstalling dropbox it was fine again.
[G2 Q&A, Help & Troubleshooting] usefulidiot127:
I started noticing this behavior using Reddit sync: If you're familiar with Reddit Sync, you scroll down a continuous page and there are repeating blocks of texts/pictures that you tap on to be taken directly to that post.

I've noticed when using the phone for significant periods of time, I can't scroll down the page without having my phone unintentionally selecting individual posts and taking me to them rather than scrolling. So it's as if the screen isn't picking up my scrolling motion but instead arbitrarily picks up a tap command.

Screen off back on fixes it.
[G2 Q&A, Help & Troubleshooting] billykxda:
Yup - phantom touches. REALLY frustrating. Nothing you can do about it other than to turn the screen off/on.

I've been having this issue surface every day lately. The only difference I see in my usage patterns is that I am using the G2 a lot. It's not the case that everyone's G2s will act up when they use them heavily, but heavy usage is definately a corollary.

LG - are you listening???
[G2 Q&A, Help & Troubleshooting] halaros2:
Touchscreen issues

I know that this problem is not exactly the same with the one mentioned in OP but i thought i d share with you since it is a touchscreen issue. Just check the responsiveness in horizontal position and then when i lift the phone from it s place LG surely must have messed up with this calibration.

P.S i Tried many times calibrating gestures movement sensor but still nothing fix this issue!!! Really very frustrating!!! I think i ll return it at the shop i bought it and check all others they have in stock just in case i find one working!!! Really a shame for such a great phone!!!

Geez - sorry to hear/see this (thanks for the YouTube link). I don't see this issue at all on my G2.

I would suggest starting a new thread specifically on this issue, since as you indicated, it's OT for this thread.

I think you might get a better/quicker response if you do.

Good luck!
[G2 Q&A, Help & Troubleshooting] WolfR1:
I've seen this issue on my G2. It is not consistent but is regular enough to be maddening. My G2 seems to exhibit this problem the more I use it in a short amount of time. For example if I play a game for a few minutes (Scramble w/Friends) then watch video highlights (via a hockey app) then I start seeing the random clicks. Sometimes in the Scramble game I see random words pop up that are part of the word I was trying to choose but not the exact word itself.
[G2 Q&A, Help & Troubleshooting] billykxda:
"Maddening" is a good way to describe living with this software defect. Using the G2 intensely will occasionally cause it - this is the only trigger I've found that is somewhat repeatable, although not totally reliable.

I continue to try to get LG's attention, but no dice so far - on any front.

[G2 Q&A, Help & Troubleshooting] linksmask1:
The maker of this video "LG G2 Touch Screen Issues" that is linked to in the 3rd link of the this thread's first post, said in a comment below the video that "LG said they'll address the issue with kitkat update due to it affecting a small number of people."

Dunno if this is true, and if LG will actually fix it. And of course don't' know when a kitkat update will come out...
[G2 Q&A, Help & Troubleshooting] billykxda:
Yeah - I saw that.

I agree with you - it's too hard to tell who you are talking to. Is it an LG/VZW person that actually knows what they are talking about, or a call-center person who's just making this crap up. Who knows?

is this not effecting the D802? i have one in the UK i imported from HK and i havent seen any issues? when did it start for you guys?:confused::(
[G2 Q&A, Help & Troubleshooting] billykxda:
As far as I can tell, all variants are affected.

As stated in the OP, there should be no worries if your G2 does not exhibit this problem - no need to go looking for it. The issue appears to be based one's usage patterns. This is probably why there are many reports of G2 owners going through 3 or 4 replacements, only to find that each has exactly the same problem. It may very well be the case that the manner in which they use the device is what causes the problem behavior. These usage patterns include "getting busy" on the device, such as extensive typing, lots of browsing, scrolling lots of lists, playing videos. Every owner will say - Hey I do that, but I don't see any problem. That's because they might not really be working the G2 as extensively. In addition, for those of us that do, the issue is not 100% repeatable - even when you replicate your "busy" usage pattern.

It's frustrating!

So, if you don't see any erratic behavior in your G2, that's great. Just enjoy it!

[G2 Q&A, Help & Troubleshooting] billykxda:
One faster way to confirm that the G2 is in "spazz mode" is to simply hold your home screen mid-transition to a neighboring screen (50% of each screen). If it's in this spazz mode, the screen will jiggle back/forth horizontally. Takes just a second to confirm.

Had my 3rd chat with an LG rep via the live chat feature on their website.

He told me that he wasn't aware of any touchscreen problems and I would have to send in my phone at my own expense (+2 weeks for phone getting there and back).

This is my 5th or 4th d800, I lost track. I simply told him to notify the tech people. I will probably keep messaging them asking for a confirmation from a tech person until they do something about it.

I returned my s4 and was going to get a g2 until I saw this thread.

Thanks for reporting the problem and trying to get lg to do something about it.

It amazes me how little lg seems to care, considering they are hanging onto the mobile market by a thread.
[G2 Q&A, Help & Troubleshooting] total_noob_1:
I'm not to sure if this has been anybody else's experience but when I have the screen on 100% brightness my screen acts funny.

I have had to return my g2 and have it fixed by LG because my last screen had gotten a dead spot after only two weeks of usage.

The phone was returned and I had the brightness all the way up and noticed the screen was "overly sensitive". I have gone using auto brightness and not going full power and have had no issues lately.
[G2 Q&A, Help & Troubleshooting] billykxda:
Interesting - thanks for sharing.

Next time my G2 spazzes-out, I'll try changing brightness settings to see if there's any variance in the erratic behavior - although I doubt it. To date, this issue looks like it's 100% attributable to a software glitch - but who knows? I'll give it a try. If someone beats me to it, please post results back here.
[G2 Q&A, Help & Troubleshooting] byproxy:
just figured i'd chime in as one more person with issues. on the verizon g2.

i get phantom scrolls, jumps, and zoom-ins/outs quite frequently - especially in the facebook and chrome apps.
[G2 Q&A, Help & Troubleshooting] gotwillk:
having auto brightness on or off does not fix the issue. i've been using auto brightness since day one and i've had the issue. turning auto brightness off also has same issue. i had it set to 50% for a while. completely bypassing LG's brightness settings by using Lux instead also has same issue. so its definitely not related to brightness settings.

what i've noticed is that the issue seems completely random to me. sometimes i don't even have to do anything. i turned on the screen, started trying to swype a message, and i got the issue already. and this was from turning on the screen just a few seconds before and without doing anything else. also i noticed that the intensity of the spazzes are increased right after i play a flash video in the browser, instead of youtube.
